Higashi T, Saga T, Ishimori T, Mamede M, Ishizu K, Fujita T, Mukai T, Sato S, Kato H, Yamaoka Y, Matsumoto K, Senda M, Konishi J: What is the most appropriate scan timing for intraoperative detection of malignancy using 18F-FDG-sensitive gamma probe? Preliminary phantom and ...
However, there is always a trade-off between the radiation dose and image quality and the contrast dose (potentially nephrotoxic) is relatively high, resulting in a limited use of CT for repeated scanning. The commonly used parameters include: BF, BV, MTT (mean transit time) and permeability...
On PET a clear hot spot (arrow) is found with increased FDG uptake, while on CT it was not recognised as a local recurrence (arrow) Full size image Finally, most included studies evaluating whole-body CT were performed around the year 2000 and it should be taken into account that since ...
The most important diagnosis that requires a prompt CT scan of the brain is acute stroke or traumatic brain injury. CT provides information on the state of the brain parenchyma, the blood vessels, and brain tissue perfusion in patients with acute stroke; information necessary to make an adequate...

In this section I'll talk about PEACH Reality as a whole, as well as the challenges we encountered during the development process. Viewing raw CT scans initial experiments The challenge has been to come up with a seamless pipeline from the raw CT scan data to holographi...
we also know that in locations with less curvature, ECG-gated 2D DIR scans with in-plane resolution of 0.25 mm have optimal vessel wall delineation, as shown in Fig.2c. These measurements were validated against histology and ultrasound in a pig model [34], and resulted in a mean carotid ...
The aim of the study was to assess the accuracy of quantitative SPECT/CT imaging in a clinical setting and to compare test results from two nuclear medicine departments. Phantom studies were carried out with two gamma cameras manufactured by GE Healthcar
